Abstract

In the title complex, [Ag2(C12H8N2O4)(C14H14N4)]n, one AgI ion, lying on a twofold rotation axis, is coordinated by two N atoms from two 3,5,9,11-tetraoxo-4,10-diazatetracyclo[5.5.2.02,6.08,12]tetradec-13-ene-4,10-diide (L) ligands in a nearly linear arrangement. The other AgI ion, lying on an inversion center, is coordinated by two O atoms from two L ligands and two N atoms from two 1,4-bis(imidazol-1-ylmethyl)benzene ligands in a distorted square-planar geometry. An additional Ag⋯Ag [3.0119 (3) Å] interaction links the AgI ions into a chain along [010]. The two types of ligands have mirror symmetry and connect the AgI ions into a layer parallel to (100).

Highlights

N atoms from two 3,5,9,11-tetraoxo-4,10-diazatetracyclo[5.5.2.02,6.08,12]tetradec-13-ene-4,10-diide (L) ligands in a nearly linear arrangement
The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2
